I. COMBINED TUBENG BLEEDER, VALVE, AND TRAP.

Application filed April 13, 1927. Serial No.-183,5i30.

yThis invention relates to new and useful' improvements 1n combined tubing bleeders,

valves and traps. f V.

` The principal .object of the invention is to provide aneconomical device for use in a pumping well, whereby the standing'valve 'may be combined with a tubing bleeder and av-sand trap.

Another object of the invention istor provide in connection with the ystanding valve a Simple screen located below the valve seat so `as to keep outtrash and other foreign matter which might lodge on the valve seat to permit the' sand to settle down into lsaid trap out oi the path ofthe' upwardly {iow- The advantagevoit such an aringl fluid. such sand cutting out the pump cups as vwell as wearing out themetal parts.

A further object et theinventionis toprovide the device. in lsuch tormthat'th'e sand trap may be omitted or added theretor asis desired.

Qne et the im sortant features of my in vention .is the provision Whereb)7 the bleeding ot the tubing 12 which extends to ther top' ofi the WellF may be carried out.. -lllhen it desired to remove the tubing, it would, of course, be full of fluid because the valve 36 Would be s eted end the luid could not es cupe. .ln order to bleed the tubing, n. vbell fr. is dropped down through the seme into the borrel 10. This bull is dedected by the gui .e 29 and is of such diameter to lodge between the spring! cage 32 und the inclined lip ot' the guide member 15.l It will be eeen that the bell valve 36 is confined Within the lower end oit' the @tige 32 and said lovver end is not attached to the ring 33.

This errang-ement permits the pin to be screwed into tubing, end tubing ot smaller dimneter to be screw-ved into the box. At the upper end of the boi-r a counter bore 44 is formed end beingi of'less iemeter than the box may receive a. still nipple 2,6 und' vupper end.

spaced transverse apertures 62 for receiving smaller tube.v kThe head has a central bore 45surrounded by a shoulder 46 on which a' screen 47 is mounted; .TheY portion 41 ot thehead is provided with a cent-ral' screwthreaded socket 48 into which the lower end oia nipple 49 is screwed. Thisnipple, like the nipple 26, has abushing 50 countersunk in its upper'endand confined by a )cap ring 51 screwed onto the nipple, as is shown in F ig. k8. end Withiannular valve seats 52 and when one is worn, said bushing may be inverted to present a new seat.

At the upper portion of thebarrel, I 'provide an internal -annular shoulder 53 tor re ceiving the lugs 54 of a valve cage 55. A This valve cage is of open construction, as is shown inFigs. 8 and 10, having V,vertical portsy 56 and a continuous ring 57 at its lower end. A coiled spring 58 resting on the head within the barrel engages Ythe lugs 54,` thus resiliently supporting the cage.` y

. The lower end of the cage is spaced above the bushing 50 and` contines'v a valve ball 59,

which is free to move vertically in the cage,

butengages on the seat 52 to close the valve. The upper end of the cage is reduced and provided with a central screw-threaded bore 60, for receiving the lower screw-threaded end of astem 61, which is pointed at its The lstein has` a plurality of a locking pin 63' mounted in t-he cage and whereby the Vpin is fastened against rotation. Thelower end 64 of the pin is rounded so as notto'injure the ball 59 when the' latter; is-displayed upwardly. By removing the pin y68and Jadjusting the stein downwardly into the cage, the l0w1erend-64 forms a stop yfor liinitingt-he upward displacement ot thev valve, .thus controllingfthe;passage of ilu id i -from the nipple 49.

. It willbe seen that by displacingthe up-y per end ot the Steinf61` horizontally, the cage will .beY rocked on one of itslugsf54, whereby thering will be swung to one side, thus rollingftheball 59 from its seat l52.' vThis rocking or canting ot' the cage will, effectual- .ly unseat the valve for the purpose of bleeding the,` tubing. In Fig. 9 Lhave shoWna tripping weight whichl isopp'ositely bevelle'd at its ends, so that when itis dropped inthe tubing, its lower bevelled end will engage the upper pointed .endet the stem v61,',

andthus'swing said steintfo one side.

In Figs. 12,713 and 141 have shown another forin, the upper'fportion of which is substantially the saine as that shown in Fi 8, the difference residing in the addition of a, sand trap kat the lowerk end.. Insteadof the heady 40, an yexternally screw-threaded head 70 is engaged with the threads 14 and yscrewed into the llower end of the barrel 10.Y

This head has an annular surrounding flange 71 engagingpthe lower edge' of the barrel The bushing' is provided at each.

boi; so that fluid may enter said duct on each side from the groove 7 4. An annular sand groove V77 surrounds the socket 48 so that sand which` passes through the screen 4T and falling back into the barrel will be caught in said groove. Inclined lugs 78 are provided in the upper portion of the groove, as is best shown in Fig.. 13, andy are used to support the coiled spring 5 8. A'

pairot ducts 79 lead. from the' bottom vof the" groove 77 on'oppositey `sides down through 'the head to the boi: 78.' Any'suitable sand 'A collecting receptacle, suchas the plug 20, may bel screwed into the-box 73. It willbe noted that the head `40 can be disconnected from the barrel'and the head 70 substituted therefor.
